I don't have room for a compressor with all my other important stuff (fishing/golfing gear) so I use this little gizmo that works like a charm. A little patience is required but it gets the job done and don't cost a bunch or take up space.

Dennis, great system. For those who like to use their built-in compressor, you can accomplish the same thing by purchasing an on-line gauge with a "bleeder valve".

My objection, for me, to this system is...

1) On my RV, if I start my engine without bringing in the slides and retracting the jacks, my alarm ( HWH jacks down) goes wild. I often want to check my tire pressures and make adjustments a day or so before we break camp so this does not work for us.

2) Maybe I'm just slow, but it takes time for me to check & if necessary fill six tires. I find leaving my diesel idling long enough to retract my jacks, air-up my brakes and the check six tires is just too long to subject my neighbours to this disturbance.

Since space is not a problem for us, the portable compressor is a preferred way to go. Nevertheless, I appreciate that the on-board compressor is also a great option for many and well worth consideration for anyone with space/storage issues.

Very good points but I am such a pack rat and carry almost everything I can think of that I "Might" need. So, I have to shuffle to get my golf clubs and fishing gear stored at times so putting another piece of machinery in the basement is not an option. The folks next door will have to put up with me filling my tires but I don't check out early in the AM so I don't feel too guillty.

Just curious on #2, how long do you idle your engine before driving off?

Perhaps my post was a bit confusing.

We use a portable compressor to fill our RV tires, if needed. My objection to the on-board compressor system is the idle time to fill air suspension, air-up the brakes, retract jacks....and....then start the whole tire routine.

Normally, we bring-up our jacks using "quiet" battery power (turn key to aux) or the "jack's down alarm" will be howling.....and only idle the MH long enough to fill the suspension & air-up the brakes (couple of min.)....then we're off!

I bought the Porter Cable compressor Jack! Thanks a lot for the tip!
After 2 trips to Home Depot, I got all the right parts for quick connect for everything. I started with a quick connect coupler so I could throw my 50' hose on if I wanted. This little compressor will come in handy when I want to pin nail something and don't want to bring out the big noisy compressor I already have!

Your local Home Depot (Canada) stocks the Sears compressor, under the Porter Cable brand name. This is widely recognized on this forum as the most effective unit out there. We purchased ours at the Home Depot in Kelowna...great unit!

I have a 12v 150 psi air compressor that I got from Harbor Freight. Cost me almost $50 when it was on sale and I had a 20% Off coupon. Just make sure you get the 150 psi model. If you look at the post immediately preceding this one, the Harbor Freight 12v/150 psi looks exactly the same as the Viair 12v/150psi model at about one third the price.

P.S. I have been using mine for 6yr. to top-up my MH tires @ 90psi and also for blowing up our bike tires 50psi.
